How to Download and Install Windows 10 Technical Preview for Phones

Windows 10 Technical Preview for phones is now available to download. This is a pre-release version of Microsoft's upcoming mobile operating system. You should only download this if you want to try a new operating system on your Windows Phone device. Since this is beta software, many of your favourite apps may not work on it and upgrading to it right now is not recommended on your primary phone as the preview is still very much a work in progress.

If you have a spare Windows Phone device lying around or if you love playing around with latest (potentially buggy) builds of operating systems, then read on.

Supported devices

Currently, Microsoft says only six Lumia phones can download and install Windows 10 Technical Preview for phones. These are:

Lumia 630

Lumia 635

Lumia 636

Lumia 638

Lumia 730

Lumia 830

More phones will be supported in future builds, but for now only users of the phones listed above can try Windows 10 Technical Preview.

Here you'll have to choose between receiving OS updates as they're released or after some bugs have been fixed. Tap Insider Fast to stay on the bleeding edge or pick Insider Slow if you'd like a slightly more reliable build.

Take a look at all the warnings and then tap Accept.

Tap the Windows button on your phone.

Go to Settings > Phone Update.

Tap Check for updates.

Now you'll be able to download the latest Windows 10 builds for your smartphone. Tell us about your experience with Windows 10 on mobile and PC via the comments. For more tutorials, visit our How To section.
